Receipt Processor

Running Instructions

1. If Docker is installed on the system and the OS is Linux, run ./run_server.sh. It will build the docker image and run it. The server will be serving requests at 127.0.0.1:8000.
2. If you are running the application on an OS other than Linux, then you can look at the two docker commands inside run_server.sh and run them on your own.
3. If docker is not installed, run python3 server.py. This will run the server, and it will be serving requests at 127.0.0.1:8000.

Notes

1. The regex for retailer is possibly incorrect in the api.yaml file. The given regex is ^\\S+$. This does not accept spaces. However, one of the examples is M&M Corner Market. I think the correct regex could be: ^[\ \S]+$. This is what I have used in utils.py
2. I have created two classes Receipt and Item in receipt.py to encapsulate incoming data into an object.
3. I have added all regex patterns to utils.py which is used in both server.py and receipt.py
4. For the GET request, I am doing input validation even though input is just a string that is being checked in the dictionary. This is because, in reality we would have a database and it's good practice to do input validation before querying the database.
